Today
The quantity of pollen grains in the air for Tuesday will remain relatively stable in the moderate range. This is a result of stable temperatures. No change doesn't mean no pollen, it just means that pollen producing plants are delivering pollen at a steady pace.
Outlook
The quantity of pollen grains in the air for Wednesday will be falling in the moderate range. This relief in pollen levels is caused in part by rising humidity, weakening winds and expected precipitation in the evening which tends to wash pollen out of the air.
